YieldReaction ConditionsOperation in experiment
20% With potassium carbonate; silver(l) oxide;dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2; In tetrahydrofuran; at 80℃; for 16h; To a flame-dried, thick-walled vial was placed 2C (1.085 g, 2.076 mmol), <strong>[886747-03-1]pent-4-enylboronic acid</strong> (0.757 g, 6.64 mmol), silver oxide (1.203 g, 5.19 mmol), potassium carbonate (1.722 g, 12.46 mmol), and PdCl2(dppf)-CH2Cl2 adduct (0.170 g, 0.208 mmol). The vial was purged with argon for several minutes and then degassed THF (8.3 mL) was added. The vial was sealed with a teflon-coated screw cap and the black suspension was warmed to 80 C. After 16 h the reaction was cooled to rt. The reaction mixture was diluted with EtOAc, washed with water, sat. sodium bicarbonate, brine, dried over sodium sulfate, filtered and concentrated to give an orange-brown residue. Purification by normal phasechromatography yielded a clear, colorless oil which was a mixture of 2D and starting material. The material was purified further by reverse phase chromatography. The pure fractions were neutralized with sat. sodium bicarbonate and then concentrated to remove the organic solvent. The remaining residue was extracted with EtOAc (2x). The combined organic layers were washed with brine, dried over sodium sulfate, filtered and concentrated to afford 2D (0.21 g, 20%) as a clear, colorless oil. MS (ESI) m/z: 512.6 (M+H)+.

YieldReaction ConditionsOperation in experiment
55% With caesium carbonate; In 1,4-dioxane; at 90℃; for 18h; 3rd Generation RuPhos Precatalyst (0.247 g, 0.30 mmol) was added to a degassed mixture of 5-bromo-1-((2-(trimethyl silyl)ethoxy)methyl)-1H-pyrazole (4.1 g, 15 mmol), <strong>[886747-03-1]pent-4-en-1-ylboronic acid</strong> (2.19 g, 19.2 mmol) and cesium carbonate (9.64 g, 29.6 mmol) in 1,4-dioxane (120 mL), and the reaction was stirred at 90 C. for 18 h. The reaction mixture was cooled to r.t. and then diluted with water. Aqueous sodium bicarbonate was added, and the resulting mixture was extracted with ethyl acetate (3×). The combined organic layers were dried over sodium sulfate, filtered, and concentrated under reduced pressure. The resulting residue was purified by flash silica chromatography, elution gradient 0 to 50% ethyl acetate in hexanes, to afford 5-(pent-4-en-1-yl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazole (2.2 g, 55%) as light yellow oil. 1H NMR (DMSO-d6, 27 C.) 0.00 (9H, s), 0.75-0.93 (2H, m), 1.66-1.88 (2H, m), 2.15 (2H, q), 2.61-2.85 (2H, m), 3.44-3.61 (2H, m), 4.92-5.22 (2H, m), 5.43 (2H, s), 5.89 (1H, ddt), 6.18 (1H, d), 7.42 (1H, d).
